Key Stage 3 Science - Physics Question 19 of 35
Calculate the force applied in newtons) if a pressure of 150Pa is acting on an area of 25m².

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

real, smaller and upside-down.   so the answer should be b.
